FOSSILS OF NEW JERSEY
Age - Tertiary Commonality - Uncommon
The cutting-grasping dentition of the cow shark is unique and makes
these teeth highly distinctive. Identification of the
different species is difficult, several distinctive tooth
forms occur within each species along with differences between the
sexes. To compound the problem the teeth are
fragile and most specimens are found broken.
A very nice specimen of Notorhynchus primigenius from Aurora.
